driconf isn't very useful at all for gallium drivers.
For r300-r500 based cards you can expect max out at around 60% of the performance the proprietary driver was giving you, I've seen it do better but only for obscure things. You're actually getting similar FPS to what I have on an IGP two generations later than yours, so be happy
